As told before - he thought that the fourth year at Barcelona was too much as his influence and effect on the players diminished. He said that either most players would have had to be changed or the coach. At Bayern you had the feeling at the end of that 3 years that the players were "sucked out". That is why I thought that even if I loved the way he let us play etc. at the end I thought it was the right time. Just that Ancelotti was the wrong choice as successor.
I do not think he is that interested in titles - he is more interested into the style of play - more into getting the players onto top level and playing like he wants them to play.
I do not see him as City's Ferguson - but it could be that he makes it four and not just 3. But what do I know. We will see it.
The school for the kids - I doubt that this is important. All big cities have excellent international schools.
